How many folks have installed spacers or adaptors to add more clearance behind the wheels, like to install Brembo calipers? Have you had any problems?

 

I used 15mm (5/8") wheel spacers to clear brembo brakes on a 2010 mustang with GT/CS wheels. The wheel clears the caliper by 1/16th or less. I had to cut off the ends of the factory studs to bolt the wheel up. Looks great

I just found these while deleting build pics

 

Pretty close but it clears

 

Wheels needs these pockets in the back to run the 5/8" spacer

 

From the back, bumper is off the car. You can see it doesn't stick out with these wheels.

 

If I would use spacers, I would only use H&R. They have a TÜV Gutachten for the S197 and therefore are safe to use up to the maximum speed on the Autobahn. They even list all tire/wheel combinations with Max back spacing in there to ensure no rubbing while hard cornering or high speed dips/bumps with necessary modifications.
Just my 2 cents.

Isn't this info best learned the hard way? Just j/k

Lexiion you would never use spacers on your car because they didn't come factory on any year of Shelby

All joking aside that's why I went with 5/8" spacers instead of something more aggressive. If I don't break any of the wheel studs with slicks this race season I would figure they are fairly high quality. They weren't cheap and they looked nice, we will see.

 

I actually had them on my FiST. And yes, no spacers ever on the Shelby.

I put on 1" spacers - works great looks great no shaking or vibrations at speed (150)mph
